BOTTLE-SEAL.

SPECIFICATION forming part of Letters Patent No. 753,245, dated March 1,1901.1.

Application filed September 15, 1903. Serial ND- 173,238. (No model.)

l MAN, a citizen of the United States, residing at New York city, in theState of New York, have invented new and useful Improvements inBottle-Seals, of which the following is a specification. Y

My invention relates to improvements in bottle-seals; and the object isto provide an improved bottle-seal which is simple in construction,eifectiveand durable in attaining the purposes of its use, which isreadily and conveniently applied and when applied will effectively sealthe bottle, and which may be readily released and removed bymanipulation without the intervention of a tool. My improvements alsoembody with such a seal a bottle formed with a projecting annular beador ridge about its mouth and a shouldered groove about the bead andoverhanging the same.

The improvements consist in the novel construction of parts and theiraggroupment in operative combination, as will be hereinafter specified,and the novelty asserted particularly pointed out and distinctlyclaimed.

My present improvements are intended and designed as an improvement onthat certain bottle-seal shown and described in my earlier LettersPatent, No. 716,392, dated December 23, 1902, wherein is shown anddescribed a bottle-seal with an integral laterally-expansibleretaining-ring lying flat on and in contact with the top of the disk orstopper .and extending beyond the periphery thereof. This device servesthe purpose with reasonable certainty and effectiveness; butto increasethese desirable and essential qualities in a bottleseal I turn or curvethe body of the retainingring or circular tongue upward in cross-sectionon amedian line, so that it will expand into a seat in the mouth of thebottle and engage with its upper edge under a shoulder, thereby securelylocking the seal or stopper against removal by gaseous pressure fromwithin.

I have fully and clearly illustrated my improvementsin theannexeddrawings, to be taken as a part of this specication, and to whichreference being made, Figure 1 is a vertical sectional view of abottle-neck having my improved bottle-seal applied. Fig. 2 is a planview of a blank cut out to form the disk or cap and the retaining-ring,the portion of with the retaining-ring or tongue and finger-k piececomplete. Fig. 4 is a perspective view of the'bottle-seal complete. Fig.5 is a plan view of thedisk or cap with the retainingring orrtongueprovided with a nger-,piece terminating in a circular disk.

In the drawings where similar parts appear in the differentillustrations they are designated bythe same reference-notations.

,A designates the bottle-neck, formed adjacent toits mouth with acomparatively broad interior annular groove or recess l, preferablysomewhat iiared in upward direction, as shown, and terminating at itsupper end or border in an overhanging shoulder 2, under which the upperedge of the retaining-ring engages and is held. At the lower end orborder of the recess 1 a shoulder is formed with an annular bead orridge 3, closely adjacent to the interior and behind which is a circulargroove 4. This formation of this lower shoulder affords a certain andsure sealing-seat for the cork or other compressible part constitutingthe sealing element of the device, since when the cork is forced downinto place its under surface will be made to conform to the vcontour ofthe bead or ridgeand enter the surrounding groove and tightly seal thebottle against escape of the gas from the inside or the ingress of airlfrornthe outside. In its natural form or shape the cork or seal 5consists of a circular disk of the proper size to readily enter themouth of the bottle and fit l over the Vopening in theneck,substantially as shown in the drawings.

To make the bottle-seal, a sheet-metal disk 6 is cut or stamped out andintegral therewith a`r'etaining-ring or tongue 7. At lthe base of theretaining-ring --the metal ofthe disk'is slit, as at 8, so that theannular depending flange 9 may be formed on the disk without distortionor displacement of the metal of the disk or cap and so that the base of.the retaining-ring may be turned up and IOO over the disk, asindicated. The depending annular flange may then be formed and the diskand flange thus made to form a cap in which the cork 5 or other yieldingand elastic seal or closure is arranged and held, and then the tongue orring is turned or bent in crosssection to the proper shape lorformation, so as to stand when turned over and down on the face of thecap with its outer edge directed upward and outward to overhang theperimetral edge of the cap. The free end portion 10 of theretaining-ring is stamped to reach inward and lie at on the face of thecap to serve a's a linger-piece by which the retainingring may bemanipulated and the seal be released and removed This linger-piece mayconsist of a plain extension or it may terminate in a circular disk 11,as seen in Fig. 5 of the drawings. The retaining-ring thus made is thenturned over and down on the face of the cap with its turned-up edgeextending beyond the peripheral edge of the cap, and because of theyielding and resilient-character of the material of which theretaining-ring is' made it may be contracted to pass into the mouth ofthe bottle and then expand into locking position with the upper edgelodged under the shoulder 2 of ythe bottle before or at the instant thesetting implement is released in pressure. tool may be used to effectthis locking. The retaining-ring being integrally connected to the cap,it is utilized as the means for releasing the seal and removing it fromthe bottle, because the ring may be withdrawn or removed by simplygrasping the free end of the ring and drawing it from its seat and thenexerting force suficient to tip-the cap and cork and vlift the wholeout.

Having described my invention, what I claim isl. A bottle-seal formedwith an integral laterally-expansible retaining-ring lying on the top ofthe stopper with its lower edge on the stopper and its other edgedirected upward and outward. Y

2. A bottle-seal formed with an integral retaining-ring disposed in avertically-curved direction on the topof the stopper with its lower edgeresting on the stopper and its outer and upper edge extending beyond theperimeter thereof.

3. A bottle-seal formed with an integral retaining-ring curved incross-section and directed upwardly and outwardly and disposed on top ofthe stopper with its upper edge extending beyond the perimetral edge ofthe stopper.

4c. A bottle seal or stopper comprising a capdisk, a retaining-ringhaving its base integral Any suitable contractile-spring therewith andarranged to lie on the cap and curved in cross-section and standing withits upper and outer edge adapted to be resiliently expanded beyond theperimetral edge of the cap.

5. A bottle seal or stopper comprisinga capdisk, a retaining-ring havingits base integral therewith and curved in cross-section and lying on thecap-disk with its lower portion, and with its upper portion directedoutward and extending beyond the perimetral edge of the cap, and formedwith an inwardly-turned flat linger-piece extending inwardly on the faceof the cap.

6. A bottle-seal consisting of a stopper, a disk-cap on the stopper, anexpansive retaining-ring having one end integral with the cap and itsbody bent in cross-section and disposed with its lower edge on the faceof the cap and its upper edge extending beyond the perimetral edge ofthe cap, and its free end extended to form a linger-piece adapted to lieiiat on the surface of the cap.

7. A bottle-seal comprising a stopper of compressible material, a metalcap secured on the stopper, an expansive retaining-ring having its baseintegral with the cap and curved in cross-section to lie on one edgeupon the cap with its upper edge reaching beyond the perimetral edge ofthe cap and having a flat extended free end portion adapted to lie flatupon the face of the cap, substantially as described.

8. A bottle having its neck formed with an interior annular recesshaving an overhanging shoulder at its upper end and a shoulder at itslower end formed with a bead or ridge, and a circular groove behind theridge, combined with a stopper, and a cap into which the stopper isfitted formed with a retainingring lying on the cap and bent incross-section to lie with one portion on the cap and the other extendingoutward and upward to expand and engage under the overhanging shoulderof the recess in the bottle-neck, substantially as described.

9. A locking-cap for a bottle-stopper, consisting of a flanged metal capand an expansive retaining-ring having one end integral with the cap andformed of a strip of sheet metal bent in cross-section on a :median lineand arranged to overhang the edge of the cap, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
